CSL533 High Heat Non-Corrosive Sealant

CSL533 High Heat Non-Corrosive Sealant

Form-in-place gasketing for industrial assembly and maintenance.


HighTempA resizeCSL533 is a one-part, moisture curing RTV (Room Temperature Vulcanizing) silicone sealant that cures to a tough rubber gasket that can be used in corrosion-sensitive applications with no adverse effects.

CSL533 is designed to maintain maximum performance and remain permanently flexible in a continuous temperature environment of 315°C (600°F), intermittent exposure up to 343°C (650°F).

CSL533 also provides excellent resistance to vibration and shock and severe weathering conditions.

CSL533 has superior resistance to oils used in mechanical and automotive systems.

CSL533 has superior adhesion to most substrates.


  • Extreme temperature performance
  • Oil resistance
  • Superior adhesion and flexibility
  • Remain permanently flexible

CSL533 is used in a wide variety of high temperature automotive and industrial applications requiring high adhesion. It replaces almost any cut gasket by making reliable form-in-place gaskets that resist cracking, shrinking and migrating caused by thermal cycling.

A high temperature neutral cure sealant is also available in a self-leveling formulation.


  • Unaffected by extreme temperatures
  • Resists moisture, vibration, mechanical and thermal shock
  • Non-corrosive
